Dear users and potential purchasers of Tamron interchangeable lenses.
Thank you for using Tamron products.
We wish to notify you that we will perform updating of the firmware for our SP 35mm F/1.8 Di VC USD (Model F012) and SP 45mm F/1.8 Di VC USD (Model F013) lens products.
SP 35mm F/1.8 Di VC USD (Model F012) for Nikon, Canon
SP 45mm F/1.8 Di VC USD (Model F013) for Nikon, Canon
Firmware update will not be required for those serial numbers.
Please check the serial numbers from the link here.
■The improvements expected as a result
1. You will now be able to use TAP-in Console (optional and sold separately) with the lens products above. (for Nikon and Canon)
2. Whereas the issue of the exposure becoming unstable under certain particular conditions when using these lenses with either the Canon EOS-1D X Mark II or EOS 80D camera has been reported in some cases, the lens firmware updating will improve for this issue. (for Canon)
■How to update the firmware
For those who require firmware update service, please contact your local Tamron distributor for more details.
